Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637974, here are decompositions:

31 + 8637943 = 8637974
127 + 8637847 = 8637974
277 + 8637697 = 8637974
307 + 8637667 = 8637974
337 + 8637637 = 8637974
523 + 8637451 = 8637974
547 + 8637427 = 8637974
601 + 8637373 = 8637974

Showing the first eight; more decompositions exist.
